I forgot apart from minato having transportable kunai's he is also holds the fastest hiraishin, or should i say his execution of the technique makes him the fastest hiraishin user.
The hiraishin speed from point A to B, is instant when Minato has used.
Tobirama has used.
Gemna and raido has used for mei.
They all got there more or less instantly.
The difference between the 3 is that minato is the quickest at utlising the technique.
So if they all started at lets say konoha and the destination was kumo and they all had seals at kumo.
Minato will reach there first.
Then tobirama
Then genma/raido/no name fodder.
Because the time it takes for genma/raido and the other guy to prepare the technique minato and possible tobirama would have gotten there already.
So while the hiraishin is instant, its the preparation/execution of the technique that determines who eventually will get to the desired location first.
If genma/raido where to fight EI, Ei would shit stomp them. Yes their hiraishin is instant, but their execution is no where near minato's, therefore its slower.
A shinobi determines at the end of the day how strong a jutsu is
Don't downplay Tobirama's Hiraishin. The only reason that Minato was able to teleport the SA is because his chakra was connected to their's via Naruto. Thus fulfilling the teleporting anything my chakra is contact with rule.
Tobirama has never been in a position where he could teleport someone who was touching his chakra. Not once, so you can't say that he can't do it just cause he hasn't shown it when its obvious that he has it. The only difference between Minato and Tobirama's Hiraishin is that Minato attached his mark to Kunai.
In fact I'm pretty sure that the bold principle is why they can teleport to their makings (Which are made of their chakra)
There is one thing i find interesting about hiraishin. Though its been stated several times that a seal is needed to teleport the user which we all know though some are starting to dispute this lol. We have found that the user can teleport something who is touching their chakra, directly or in contact with it.
Basically while the user of hiraishin needs seals to teleport themselves, with direct chakra touching they can teleport objects. However they cannot or should i say haven't shown the ability to teleport to something using just chakra like the way they do when teleporting others and not themselves. That is why the seals are so important, apart from them being incorporated with the user's chakra to form this link, they are more than that, which brings us back to the principle of the kuchiyose
just a question did Tobirama teleport them or did Minato after all sasuke and jugo still had the cloak and tobirama doesn't have sasuke or jugo marked
Tobirama teleported them in this chapter
